Functional architecture and cell wall composition of peltate scales involved in leaf water absorption [PDF]

open access: yesFrontiers in Plant Science
IntroductionFoliar water uptake (FWU) is a mechanism that contributes to plant water balance, especially in epiphytic environments. Morphological features such as the presence of peltate scales in bromeliads are adaptive traits for FWU. In this study, we

Ecophysiological Traits of Invasive C3 Species Calotropis procera to Maintain High Photosynthetic Performance Under High VPD and Low Soil Water Balance in Semi-Arid and Seacoast Zones [PDF]

open access: yesFrontiers in Plant Science, 2020
The evergreen C3 plant Calotropis procera is native to arid environments. Thus, it grows under high vapor pressure deficit (VPD), intense light, and severe drought conditions. We measured several ecophysiological traits in C.

Changes in Foliar Water Uptake Caused by Water Stress in Cattleya Lindl. (Orchidaceae). [PDF]

open access: yesPhysiol Plant
ABSTRACT In response to water restrictions imposed by the epiphytic environment, orchids have developed strategies to increase water‐use efficiency, such as the expression of Crassulacean Acid Metabolism (CAM) and the foliar water uptake (FWU). In a climate change scenario, FWU may emerge as a strategy to reduce water stress during drought.

Step by step: Floral structure and developmental changes to the formation of the gynostegium in Apocynaceae s.l. [PDF]

open access: yesPlant Biol (Stuttg)
Developmental changes in Apocynaceae s.l. reveal progressive reductions in the corolla tube and epipetaly, together with increased staminal tube formation, highlighting shifts in floral integration associated with gynostegium evolution and organization.

From flower to fruit: The origin of the trilocular ovary and fruit development in Phragmipedium longifolium (Warsz. & Rchb.f.) Rolfe (Orchidaceae: Cypripedioideae). [PDF]

open access: yesPlant Biol (Stuttg)
Phragmipedium longifolium has a trilocular ovary with a post‐genital septum, and during fruit development, lignification plays a crucial role in facilitating dehiscence and seed dispersal. Abstract While carpels in Orchidaceae are predominantly unilocular, trilocular carpels can also occur, mainly in branches separated during the early diversification ...

Auxin-Dependent Activation of RHD6-RSL4 Cascade Promotes Root Hair Growth Under Boron Deficiency in Arabidopsis Primary Root Apices. [PDF]

open access: yesPlant Cell Environ
ABSTRACT Plants rapidly adjust their root system architecture to enhance resource uptake and cope with fluctuating soil environments. One such adaptive response is the development of root hairs (RH), which increase the effective root surface area and thereby improve water and nutrient acquisition.
